Abstract

Segments of welded small-bore A-106 carbon steel from a piping system that experienced severe flow-accelerated corrosion were characterized for surface damage due to flow-accelerated corrosion (FAC). A computational fluid dynamics (CFD) analysis was done to compare findings of CFD model versus observed surface FAC damage inside the pipes. CFD results expressed in terms of turbulence intensity showed good agreement with actual surface damage due to FAC. It was concluded that the presence of internal grooves would cause turbulent flow regime, and therefore, it would cause pipe material damage.
